I am trying to setup an SSL certificate on my droplet. However it is not working, and I don’t know how to troubleshoot it for issues that I can then go and correct.
In /etc/apache2/ssl-certs i have my certificate, intermediate certificate and keyfile
In /etc/apache2/sites-available i have 2 files which were with the droplet on installation - 000-default.conf and default-ssl.conf.
I have followed instructions from https://www.digitalocean.com/community/tutorials/how-to-install-an-ssl-certificate-from-a-commercial-certificate-authority but when I try to go to my site under https nothing happens.
so… how can i troubleshoot this to find any errors? do i need both of those original conf files or will 1 be enough? I have never setup SSL before and so am really stuck. Any help at all would be really appreciated.
Thanks.

I have checked out many of the tutorials. Thanks for your replies. I am doing this for a client and I am now starting to think I have everything setup correctly,… but it is the client who has not yet setup the relevant subdomain that I was asked to create the certificate for.
I have used this awesome tool https://www.sslshopper.com/ssl-checker.html and checked :
https://my-ip-number - This shows that my certificates and intermediate certificates are setup correctly, the only issue is that the url and certificate common name are different.
https://myclient.subdomain.co.uk - This shows errors.
I used this tool: https://pentest-tools.com/information-gathering/find-subdomains-of-domain
To scan all subdomains of my clients url and sure enough it showed that the sub-domain they requested I setup an SSL certificate for has not been created / point anywhere. So i’m pretty certain this is the issue. Both those tools above are very useful and will come in handy in the future im sure.
Have you checked out this DO tutorial? https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-with-a-free-signed-ssl-certificate-on-a-vps
DO tutorials are awesome. Google this “how to install certificate your_operating_system digitalocean” startssl.com givesaway free SSL certificates. They all comply with modern requirements.
